TargetDataLineTargetDataLinefrom javax.sound.sampledjavax.sound.sampledI 可以将数据读入byte[]byte[]数组 byte[] tempBuffer = new byte[10000];
fromMic.read(tempBuffer,0,tempBuffer.length);
But the problem is that the samplesargument needs short[]
但问题是samples论证需要short[]

You are lucky enough that byteis "fully castable" to short, so:
您很幸运可以byte“完全铸造”到short，因此：
// Grab size of the byte array, create an array of shorts of the same size
int size = byteArray.length;
short[] shortArray = new short[size];
for (int index = 0; index < size; index++)
shortArray[index] = (short) byteArray[index];
And then use shortArray.
然后使用shortArray.
Note: as far as primitive type goes, Java always treats them in big endian order, so converting, say, byte ffwill yield short 00ff.
注意：就原始类型而言，Java 总是以大端顺序处理它们，因此转换，例如， byteff将产生 short 00ff。
